Abstract
Abstract The present invention relates to a three-layered fabric material composed of a non-woven fabric of hydrophobic fibers not more than 1 denier in single-filament denier as the inner layer, a fabric of hydrophilic fibers as the intermediate layer and a fabric of hydrophobic fibers larger in denier than the fibers of the intermediate layer as the outer layer. Clothing made of said three-layered fabric material provides excellent heat retentivity and especially, excellent comfortableness when it is in wear.
